Trim AAC, M4A, and M4R audio on a single page. Great for ringtones, dialogue clips, and shorter recordings with a fast, simple workflow.

Why teams choose it
AAC Cutter is built for ringtone editing and quick everyday audio clipping.

Use one editor to trim AAC, M4A, and M4R files without switching tools. It is useful for ringtone creation, voice-note cleanup, music highlights, and short audio extracts.

Set your start and end points on a visual waveform, preview the clip, and fine-tune the timing easily. It is especially convenient when preparing short ringtone segments or notification sounds.
